Hi koolsid, thanks for your reply

1) I am using Excel 2003

2) I am placing the textbox directly on the worksheet

3) I was actually drawing the textbox on the worksheet using View~~>Toolbars~~>Drawing.

In actual fact, I've solved my problem now! I have just used View~~>Toolbars~~>Control toolbox to add my textbox, and can now edit the properties of it no problem, including adding a vertical scroll bar.
